Answer:
A
Step-by-step explanation:
x2 = -98
x =+-√-98
x = +-√49 • 2 • -1
x = +-7√2 • -1
x = +-7i√2
(Note: i = √-1 and i^2 = -1, so you can interchange the values)
Answer:
1/15
Step-by-step explanation:
Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?
The amount of cereal she would have per day is calculated as:
5 days = 1/3 of the box
1 day = x
Cross Multiply
5 days × x = 1 day × 1/3 of the box
x = 1/3 ÷ 5
x = 1/3 × 1/5
x = 1/15 of the box
Answer: Student X and Y
Step-by-step explanation:
Student W started off correctly as they simplified the first expression and got rid of the parentheses.

If you have to share 2 by 3 equally then that is saying divide, when you divide you get .6666 but if you turn it into a fraction it 2 over 3
Option C: (x-4)^2+(y-1)^2 = 4 is the right answer
Step-by-step explanation:
Given
Center = (h,k) = (4,1)
Radius = r = 2
The equation of circle in standard form is:
Putting the values of h, k and r
Hence,
